In connection with the OpCo and AT&T Exchange Offers, AT&T is also soliciting consents (the “Consent Solicitations”) from holders of the OpCo Notes to eliminate substantially all of the restrictive covenants in the indentures governing the OpCo Notes (the “OpCo Indentures”). As of the Early Participation Date, the necessary consents to adopt the proposed amendments to the relevant OpCo Indentures with respect to each of the following OpCo Notes were obtained: (i) 7.120% Debentures, due July 15, 2097 of BellSouth, LLC, (ii) 5.950% Debentures due January 15, 2038 of Ameritech Capital Funding Corporation, (iii) 6.550% Notes due 2034 of BellSouth, LLC, (iv) 8.250% Senior Notes due November 15, 2031 of AT&T Corp., (v) 6.875% Notes due 2031 of BellSouth, LLC, (vi) 7.875% Debentures due 2030 of BellSouth, LLC, (vii) 6.550% Debentures due January 15, 2028 of Ameritech Capital Funding Corporation, (viii) 7.300% Debentures due August 15, 2026 of Indiana Bell Telephone Company, Incorporated and (ix) 7.125% Debentures due March 15, 2026 of Pacific Bell Telephone Company. AT&T has decided to waive the Requisite Consent condition (as defined in the OpCo and AT&T Offering Memorandum (as defined below)) with respect to all series of OpCo Notes other than the 6.040% Debentures, due November 15, 2026. As a result, the proposed amendments will become effective on the settlement date with respect to any series of OpCo Notes for which the necessary consents are received. If the proposed amendments to the OpCo Indentures are adopted, all OpCo Notes not tendered or not accepted for exchange will be governed by amended indentures, which will have less restrictive terms and afford reduced protections to the holders of those securities compared to those currently in the OpCo Indentures.

No accrued but unpaid interest will be paid on any OpCo Notes in connection with the Obligor Exchange Offer. However, interest on the applicable New AT&T Obligor Note will accrue from and include the most recent interest payment date of the tendered OpCo Note.

The OpCo and AT&T Exchange Offers are being conducted upon the terms and subject to the conditions set forth in an offering memorandum (the “OpCo and AT&T Offering Memorandum” and, together with the Maturity Extension Offering Memorandum, the “Offering Memoranda”), dated October 30, 2017, as amended by AT&T’s press release, dated as of November 13, 2017 and the related letter of transmittal and consent (the “OpCo and AT&T Letter of Transmittal” and, together with the Maturity Extension Letter of Transmittal, the “Letters of Transmittal”).

The amount of outstanding Old Notes validly tendered and not validly withdrawn as of the Early Participation Date, as reflected in the tables above, satisfied the minimum tender condition in the New 2046 Exchange Offer.
